Cobalt sulfide (CoS2) nanostructures were synthesized via a simple thermal decomposition method using [Co(oct)2] as a new precursor. Using the organometallic compound as precursor could synthesize materials in nano-scale because of having the massive structure that acted as capping agent. The products were characterized by various analyses such as X-ray diffraction pattern (XRD), scanning elect...

The Hedgehog (Hh) signaling pathway has conserved roles in development of species ranging from Drosophila to humans. Responses to Hh are mediated by the transcription factor Cubitus interruptus (Ci; GLIs 1-3 in mammals), and constitutive activation of Hh target gene expression has been linked to several types of human cancer. In Drosophila, the kinesin-like protein Costal2 (Cos2), which associa...

Hydrogen evolution reaction (HER) by electrochemical water splitting using new promising non-precious metal catalysts shows great potential for clean energy technology. The design and fabrication of a high-performance electrode material based on cobalt disulfide/reduced graphene oxide (CoS2/RGO) nanocomposites is reported by a one-step hydrothermal method. Benefiting from its structural advanta...

Introduction Characterization of biological tissue structure and organization using Diffusion Tensor (DT) Magnetic Resonance Imaging (MRI) relies on effective analysis and multidimensional data visualization methods. The toroid-based representation of the DT has been experimentally demonstrated to be less prone to visual ambiguity [1] and offers additional quantitative scalar maps to evaluate t...

— The nature of point defects in nematic liquid crystals has been studied by placing droplets on a water substrate and viewing these between crossed polarizers. Three configurations are observed. These configurations are accounted for by minimizing the Frank elastic energies with suitable boundary conditions. The second order nonlinear simultaneous partial differential equations that describe s...

The generation of chemical fuel in the form of molecular H2 via the electrolysis of water is regarded to be a promising approach to convert incident solar power into an energy storage medium. Highly efficient and cost-effective catalysts are required to make such an approach practical on a large scale. Recently, a number of amorphous hydrogen evolution reaction (HER) catalysts have emerged that...

Hedgehog (Hh) signaling is crucial for the development of many tissues, and altered Hh signal transduction can result in cancer. The Drosophila Costal1 (Cos1) and costal2 (cos2) genes have been implicated in Hh signaling. cos2 encodes a kinesin-related molecule, one component of a cytoplasmic complex of Hh signal transducers. Mutations in Cos1 enhance loss-of-function cos2 mutations, but the mo...
